General information about the continuous aerator

The mixing head is executed with a double jacket, so it can be tempered to achieve an aerated product under controlled temperature conditions.

The mixing head consists of one rotor and two stator parts, all executed with machined pins. The unique design of this high shear mixer ensures very consistent final product densities.

The continuous aerator / mixer is constructed in such way that it can aerate or homogenize products with minimum heat rise.

Mixing head and drive are inline, and flanged together for perfect alignment, resulting in low noise and no vibrations.

For easy and exact density control of the final product our mixers are executed with automatic density control as standard. Once the airflow has been adjusted to achieve the desired product density, the airflow will then be automatically adjusted even when the mixer throughput is changed.

Standard features:

Information about the mixing head from the aerator:

• Mixing head constructed as “mono block” design, robust and without any foreign materials
• Mixing head constructed of stainless steel Aisi 316
• Mechanical shaft seal
• Jacketed mixing head stators
• Pneumatic operated backpressure regulator valve
• AC variable speed mixing head drive
• Direct drive SEW geared motor
• Easy CIP and simple to maintain

Product pump:

• Positive displacement pump
• Large suction port, to handle viscous materials
• AC variable speed pump drive
• Pump on separate stainless steel frame, so it can be placed underneath or very close to a product buffer tank
• Stainless steel pipe between pump and mixer
• Drain valves on lowest points of the pump and pipe work

Air dosing system:

• Automatic and manual density control
• Air mass flow controller
• Hygienic air injector
• Constant air flow even with varying mixing head pressures
• Solenoid valves to operate the air system automatically with start / stop of the product pump
